due to the utilization of technique scheme, the present invention compared with prior art has following advantages: in the anti-reverse of this escalator or moving sidewalk and anti-Motor Over Speed device, being fixedly connected with of the hollow shaft of coder and the output shaft of motor is realized by adapter shaft, rotate at the output shaft of motor like this, when outputting power drives escalator or moving sidewalk to run, the hollow shaft of coder rotates along with the output shaft synchronous of motor, electronic component in coder senses the rotation of hollow shaft, export the dephased impulse singla of twice tool to electric system, electric system can obtain the real-world operation speed of escalator or moving sidewalk by calculating the pulse period, when the real-world operation speed analyzing escalator or moving sidewalk exceedes setting value, electric system can control escalator or moving sidewalk is out of service, in addition, electric system can analyze escalator by the phase bit timing of twice impulse singla or whether moving sidewalk occurs to run reverse, if taken a turn for the worse, then also can stop the operation of escalator or moving sidewalk, avoid safety misadventure occurs, ensure the safety of passenger.
Detailed description of the invention
structure of the present invention is set forth further below in conjunction with accompanying drawing.
shown in Fig. 1-4, the anti-reverse of escalator or moving sidewalk and anti-Motor Over Speed device, comprise adapter shaft 2, coder 3, support 5, electric system, coder 3 comprises shell 31, hollow shaft 32, electronic component, the shell 31 of coder 3 is fixed on support 5, hollow shaft 32 is positioned at the center of shell 31, and can rotate around Pivot Point Center line, electronic component is arranged in shell 31, when hollow shaft 32 rotates, electronic component can sense the rotation of hollow shaft 32, then exports the dephased square-wave pulse signal of twice tool.Electronic component and electric system are electrically connected, and the dephased square-wave pulse signal of twice tool that electronic component exports can be sent in electric system, is processed by electric system.In the present embodiment, adapter shaft 2 adopts special bolt, one end of i.e. adapter shaft 2 is provided with outside thread, the end face of the output shaft of motor 1 offers tapped bore, externally threaded one end of adapter shaft 2 screws in tapped bore, as shown in Figure 2, being fixedly connected with of one end of adapter shaft 2 and the output shaft of motor 1 is realized.The other end of adapter shaft 2 is fixedly inserted in the hollow shaft 32 of coder 3, in the present embodiment, to be fixedly clamped hollow shaft 32 and the adapter shaft 2 that is inserted in this hollow shaft 32 by clamping ring 4, specifically, as in Figure 2-4, hollow shaft 32 passes shell 31, the position passed is arranged with clamping ring 4, clamping ring 4 has nonocclusive ring body, the both ends of the surface that ring body disconnects all offer threaded perforations 7, threaded fasteners 6 screws in the threaded perforations 7 at ring body two ends, realizes the clamping of clamping ring 4 pairs of hollow shafts 32 and adapter shaft 2.Then realize being fixedly connected with of the hollow shaft 32 of coder 3 and the output shaft of motor 1 by adapter shaft 2, rotate at the output shaft of motor 1 like this, when outputting power drives escalator or moving sidewalk to run, the hollow shaft 32 of coder 3 rotates along with the output shaft synchronous of motor 1, electronic component in coder 3 senses the rotation of hollow shaft 32, export the dephased square-wave pulse signal of twice tool to electric system, real-world operation speed and the service direction of dynamic staircase or moving sidewalk are come from electric system meeting computational analysis, and judge the real-world operation speed of escalator or moving sidewalk and service direction whether normal.Whether the real-world operation speed whether normally referring to escalator or moving sidewalk here exceedes setting value (whether exceeding the speed limit), or whether real-world operation direction takes a turn for the worse.When the real-world operation speed that electrical System Analysis goes out escalator or moving sidewalk exceedes setting value, or when real-world operation direction takes a turn for the worse, this electric system can control escalator or moving sidewalk is out of service, avoids safety misadventure occurs, and ensures the security of the lives and property of passenger.Electric system, after receiving the twice square-wave pulse signal of coder, can obtain the real-world operation speed of escalator or moving sidewalk by calculating the pulse period, and judges whether normal.After the phase bit timing of this twice square-wave pulse signal changes, electric system then can judge to occur reversal, thus stops the operation of escalator or moving sidewalk.
in Fig. 1-2, one end of support 5 is fixed with the shell 31 of coder 3, the other end is fixed on the base of motor 1, support 5 comprise be fixed on motor 1 base on the first carrier unit 51, support the second carrier unit 52 of the shell 31 of coder 3, second carrier unit 52 has stand connection 521, stand connection 521 by bolt directly and coder 3 be fixedly connected, first carrier unit 51 offers the oval hole vertically extended, second carrier unit 52 offers the oval hole extended in the horizontal direction, first carrier unit 51, through there being bolt in the oval hole of the second carrier unit 52, these bolts and nuts match, realize the first carrier unit 51, being fixedly connected with of second carrier unit 52.Because the position of bolt in the oval hole of the first carrier unit 51, second carrier unit 52 can regulate, then can regulate height and the level attitude of support 5, to be adapted to connect coder.
to sum up, the anti-reverse of this escalator or moving sidewalk and anti-Motor Over Speed device, when escalator or moving sidewalk run, if escalator or moving sidewalk run hypervelocity or service direction there occurs reverse, then electric system can control escalator or moving sidewalk is out of service, ensures passenger safety.
